IGNITION SYSTEM FOR EXPLOSION-ENGINES.

Specification of Letters Patent.

To all it may concern:

Be it known that I,IRICHARD VARLEY, a citizen of the United States,residing at Englewood, in the used as the sole source of primarycurrent, and batteries of every sort are dispensed with.

The use of batteries in motor vehicles is attended by I much trouble andannoyance mainly on account of the the light run-about class, and withan engine having fact that the amount of energy required for the engineignition is large and beyond the capacity of any convenient portablebattery, unlessthe same is renewed or recharged very frequently.Accordingly engine driven" magneto generators are frequently used tosupply the ignition current when the engine is'running. Such fgenerators answer requirements except thatthey do not generate a currentwhen the engine is at rest to en- In the drawings: Figure 1 is a view ofan auxiliary 1 magneto generator included in'an ignition system andembodying the principles of my invention; Fig. 2 is a detail view-of apart of the same. Fig. 3.11s detail view showing a slightly modifiedarrangement. Engines with four or more cylinders are now almostuniversally used onall motor vehicles, except those of this number ofcylinders it always theoretically possible to start the engine froma'state of rest, since one of the four cylinders is bound to be'withi'ua quarter of a.

revolution of the nornral ignition point, and the ignition timingdevices are always capable of being manipulated enough to reach theignition point for such one of the cylinders within these limits. Sincethis cylinder contains a carbureted mixture remaining from the intakewhen the engine was last running, it follows that such charge will beexploded I and the engine started. This is not only theoreticallygthecase, but ispractically true for all cars which have finelybuiltcngines. The only requisite, therefore, is to obtain an ignition sparkof suflicient intensity to ignite the charge which is often cold andonly slightly compressed when the engine has been standing idle for along time. The.

engine driven dynamo is of course not avail able when the engine is atrest.

In carrying out my invention I aim to provide a source of current whichis compact and convenient, and

which has abundant energy to 'fire a poor mixture which has been'leftstanding in the cylinders for a long time. i I further aim toautomatically cut out this auxiliaify sour'ce from action when theengine hasbeen started into operation.

Referring to the di'awings in which like part sare desig- I nated by thesame reference sign, 1 designates broadly a magneto generator which isformed to be attached upon the dashboard of a motor vehicle, and in aposition convenient to be engaged by the foot of the chauffeur or hisniechanician; This magneto generator is conveniently made with abox-shaped frame or casing 2,

open at its front side, and having screw holes 3, by

which any ordinary cover plate (not shown) may be secured thereto. 4indicate the permanent magnets received upon -polepieces 5, attached tothe-casing 2, and 6 denotes the revoluble part or armature which isjournaled in suitable bearings 7, on the pole pieces. This magneto maybe of the ordinary or any desired form, and the details of itsconstruction-constitute no part of my inven tion.

8 denotes a short shaft' journaled in the casing 2, and having a largegear wheel 9 thereon. which is geared to rotate the armature 6 by amultiplying gear train l0, l1, 12, the pinion 12 being on the armatureshaft. Gears 10 and 11 are fixed on a shaft 13 jonrnaled'in the casing.I provide meansjor rotating the shaft 8 through part of a revolution bythe movement of the foot. For this purpose a ratchet wheel 14 is fixedto the shaft 8, and a spring pressed pawl 15, carried by a lever 16,loose on shaft 8 is effective to turn the ratchet wheel 14 when thelever 16is'rocked. The lower end ofthe leverl6, is

provided with a pedal 16.

' One of the armature terminals of the magneto generator 1 is groundedon the casing 2, while the other tcrminal has the ordinary spindle endconnection with a plate 21. This plate 21 is in electrical connection bya wire 22,.with the stop or contact 18. This brush may also be connectedin the ignition circuit in the manner shown diagrammatically at th 0lower part of Fig. 1.

The operation is as follows: The induction coils A, A A and A", areconnected through any suitable'circuit controlling devices B, C, with adynamo or other suitable current source D, grounded at E. The nagnetogenerator comprised by my invention is included in this circuit, theconnection n being grounded on the casing 2, while the connection n runsto the plate 21.
